Question 7 of 10 Which best describes how mRNA is produced in a cell? A. mRNA is made by duplicating RNA found in the nucleus. B. mRNA is made by DNA, using RNA nucleotides as a template. C. mRNA is made by lining up RNA nucleotides, using DNA as a template. D. mRNA is made by breaking apart DNA and reusing the pieces.

## Step 1<br />The question is asking about the process of mRNA production in a cell. mRNA, or messenger RNA, is a type of RNA that carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.<br /><br />## Step 2<br />The process of mRNA production is known as transcription. During transcription, an enzyme called RNA polymerase uses one strand of the DNA as a template to synthesize a complementary strand of mRNA.<br /><br />## Step 3<br />The mRNA is synthesized by lining up RNA nucleotides (adenine, uracil, cytosine, and guanine) in a sequence that is complementary to the DNA template strand. This process does not involve duplicating RNA found in the nucleus (Option A), using DNA as a template (Option B), or breaking apart DNA and reusing the pieces (Option D).
